Test Procedures
Secure the test specimen firmly on the moving stage.
Select and install the appropriate scratch needle or test fixture.
Choose the required continuous or fixed load range.
Set the sliding speed and travel distance.
Perform system checks and ensure overload protection is active.
Start the test to apply progressive load during linear motion.
Observe scratch formation and record resistance data for analysis.
